Hi There

I know there are a few VDSL Geeks out there that will know a little more than me - I had to replace a modem at a customer site, everything looks good when I left site but when checking the stats I see "Service Stability Unstable"

Anything I need to be concerned about ? I have put the line in question below in italics.
